interfacing HM 7044

[vsci16]

I have a hameg HM 7044 power supply and am trying to establish a communication between this programmable power supply and the pc using a RS232 connection and the overall control through a labview VI. I am unable to find the drivers for this HM7044 from the Labview website for downloading the drivers, or through the manufacturer's website.

I'd be really grateful if someone help me in this regard?

thanks in advance

Looks like you need to develop from scratch for this instrument. You can refer to the SCPI commands in pg.24 of this manual - https://cdn.rohde-schwarz.com/hameg-archive/HM7044_D_E_F_S.pdf

This can performed without drivers.  Use the RS-232 configuration and commands on page 24 of the manual in order to remotely communicate with the instrument.

Hi, 

Thanks for your reply. So you mean the automatic control of this power supply can be done without drivers? 

Also, I'm really new to these terms so could you please tell me how I'd be able to use these commands in this page? 

Thankyou again

You will need to select the VISA resource identified by your system then send the SEL? command.

Hi,

I have the same VI as you have shown, but when I run it shows me a VISA read in error: 1073807339, and I am unable to resolve this error.

Could you please tell me how i could resolve this error and go ahead? I also ran a hyperterminal test to verify the serial connection, and it says it is connected but when i try to implement the controls through labview it gives me an error.

Thanks in advance

Does the instrument show up in NI-Max?  If it does and seems to be working properly, try to communicate under NI-Max with the SEL? command.
